Puzzle

Can you figure out the famous American city the puzzle is trying to name? I'll post the answer in a day or two if there are some guesses but nobody solves it.

Note: DIIYO, aka Wombat was the first to solve the puzzle. With his permission, I have deleted his solution in the comments so that others may continue to try.

A few hours later, "Anonymous" got it -- and I deleted that answer for the same reason.
